$\lim_{x\to-1}\left(\frac{x+1}{x^2-3x-4}\right)$
Learn how to solve limits by direct substitution problems step by step online. Find the limit of (x+1)/(x^2+1*-3x+-4) as x approaches -1. Simplifying. Factor the trinomial x^2-3x-4 finding two numbers that multiply to form -4 and added form -3. Thus. Simplifying.
